The photochemical, magnetic and warming effects of semiconductor laser on the ear points may promote the circulation of Qi and blood in the meridians, regulate the functions of the Zang-Fu organs, thus obviously improving the physiological functions. In view of modern science, semiconductor laser irradiation on the auricular points is able to regulate the nervous system and tranqualize the mind, suitable for treatment of insomnia. This therapy is well accepted by the patients for the satisfactory results with no pain and no side effects. By Yao Shuying
